Aviation experts are outraged over a YouTube video that shows a remote-controlled drone flying close to an airplane at Vancouver International Airport. The video, posted to YouTube on Nov. 4, 2013 by user Quadrotor Dragonfly, was filmed using a camera aboard the drone as it appears to fly at the same altitude as a jetliner as the jetliner passes by on its way to land at the airport.

An Expressjet E145 had to take evasive action to avoid a United 737 at Newark Liberty International last week. The Expressjet had been given clearance to takeoff on Runway 4R, while simultaneously, the United was on short approach to Runway 29. The Expressjet pilot said “it was really close”. The NTSB has launched an investigation.
